High Entropy Oxide Relaxor Ferroelectrics
Yogesh Sharma, Min-Cheol Lee, Krishna C. Pitike +13
Relaxor ferrolectrics are important in technological applications due to a strong electromechanical response, energy storage capacity, electrocaloric effect, and pyroelectric energ…
Tuning magnetic and optical properties through strain in epitaxial LaCrO3 thin films
Yogesh Sharma, Binod Paudel, Jegon Lee +7
We report on the effect of epitaxial strain on magnetic and optical properties of perovskite LaCrO3 (LCO) single crystal thin films. Epitaxial LCO thin films are grown by pulsed la…
Decoding the shift-invariant data: applications for band-excitation scanning probe microscopy
Yongtao Liu, Rama K. Vasudevan, Kyle Kelley +5
A shift-invariant variational autoencoder (shift-VAE) is developed as an unsupervised method for the analysis of spectral data in the presence of shifts along the parameter axis, d…
Designer Magnetism in High Entropy Oxides
